Answer:
The answer is False. Although sensitive cells are <u>more abundant</u> in the <u>anterior portion</u> of the annelid´s body, in general, they are arranged in all the segments.
Explanation:
Annelids, such as the earthworm, have a variety of sensory cells:
- <u>Mechanoreceptors</u>, disposed of in groups in <em><u>each segment</u></em> of their body.
- <u>Photoreceptors</u>: Light-sensitive cells. Although they are <em><u>located in the whole </u></em>body, they are <em><u>abundant in anterior and posterior segments</u></em>, concentrated in the intern and dorsal part of the epidermis.
- <u>Humidity receptors</u> are the most sensitive cells and are <u>located in the first segments</u> of the earthworm body
- <u>Chemoreceptors</u>: sensorial cells cumulus forming a prominent tubercle with prolongations that extends through the cuticle. These tubercles form three rings <em><u>in each segment</u></em> but are especially <em><u>abundant in the anterior part</u></em> of the body.
The tegument is very rich in free nervous terminations, which functions might be tactile.
Answer:
lytic
Explanation:
The lytic cycle involves the reproduction of viruses using a host cell to manufacture more viruses; the viruses then burst out of the cell
Answer:
Option-D
Explanation:
The network of neurons which gets activated in the condition of stress that is fear or anger is known as Sympathetic nervous system.
During stress conditions, this system prepares the body physically and mentally either to fight or flight by controlling the production of hormones through activation of specific neuron network in the body. Mainly the adrenaline and norepinephrine which act and produces the response like increased heartbeat, sweating and other.
Thus, D)sympathetic is the correct answer.
"Body cells<span> are </span>body cells<span> or somatic </span>cells<span> are produced by mitosis. ... </span>Gametes are sex cells, so the egg and sperm. They are considered haploid because each gamete contains<span> half the number of chromosomes that an organism's somatic </span><span>cells will have" So Gamete has 23 Chromosomes</span>
Explanation:
Because we always seek to make sense of any perceived stimulus to better understand the reality that surrounds us and act before it. Through perception we process information from the senses, with which the brain builds and tries to give meaning to those stimuli that reach it. However, each person captures, selects and organizes sensory stimuli differently and, therefore, arrives at different interpretations and responses when solving a problem, in which memory and experience also form a fundamental role. Thus, differences between perceptions help explain how people interpret the environment and why they behave differently in the same situation. For example, when we recognize a specific object, an action can be initiated, in which a motor activity is propitiated in response to that recognition, and which can be different in each person.
